Rose Plant Named &#39;Poulph111&#39;

ABSTRACT

A new garden rose plant of the Miniature class which has abundant, white flowers and attractive foliage. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical Designation: Rosa hybrida .

Variety Denomination: ‘Poulpah111’.

This application claims priority to Plant Breeder’s Rights ApplicationNumber 2021/2363, which was filed at the Community Plant Variety RightsOffice in the European Union on Sep. 24, 2021, the contents of which arehereby incorporated by reference for all purposes.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of roseplant which originated from a controlled crossing between the femaleseed parent, an unnamed seedling, and the male pollen parent, also anunnamed seedling. Both of the parent varieties are non-patented.

The two parents were crossed during the summer of 2016 and the resultingseeds were planted in a controlled environment in Fredensborg, Denmark.The new variety, named ‘Poulpah111’, originated as a single seedlingfrom the stated cross.

The new variety may be distinguished from its male pollen parent andfemale seed parent primarily by the following characteristics. The malepollen parent plant has flowers generally toned RHS White Group 155A,while the new variety has white flowers with additional tonality ofYellow Group 8D. The female seed parent plant has orange-yellow flowers,while the newly claimed plant has white flowers with tones of yellow.

The objective of the hybridization of this rose variety was to create anew and distinct variety with unique qualities, such as:

-   1. Uniform and abundant white flowers;-   2. Vigorous, but compact growth when propagated on its own roots;-   3. Exceptional disease resistance; and-   4. Production in containers.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpah111’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated theseeds from the aforementioned hybridization during winter of 2016 andconducted evaluations on the resulting seedlings in a controlledenvironment in Fredensborg, Denmark. ‘Poulpah111’ was selected in thespring of 2017 by the inventor as a single plant from the progeny of theaforementioned hybridization.

Asexual reproduction of ‘Poulpah111’ by rooted cuttings was first doneby Mogens N. Olesen in the nursery in Fredensborg, Denmark in July,2017. This initial and other subsequent asexual propagations conductedin controlled environments have demonstrated that the characteristics of‘Poulpah111’ are true to type and are transmitted from one generation tothe next.

DESCRIPTION OF THE DRAWING

The accompanying color the FIGURE shows as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems, of‘Poulpah111’. Specifically illustrated in the drawing is an open flowerviewed from above, petals detached, bare stem, partially open flowerviewed from the side, sepals detached, receptacle, pedicel, reproductiveflower parts, and leaves. Plants shown are 2 years of age.

DETAILED DESCRIPTION OF THE VARIETY

The The following is a description of ‘Poulpah111’,as observed in itsgrowth in a glass house located in Odense Denmark. Observed plants are 6months of age, and were grown on their own roots in 24 cm containers.Color references are made using the Royal Horticultural Society (London,England) Colour Chart, 2001, except where common terms of color areused.

For a comparison, several physical characteristics of the rose variety‘Poulpah085’, U.S. Plant Pat. No. 29,633 are compared to ‘Poulpah111’.The claimed plant has a flower general tonality that is initially YellowGroup 8D becoming White Group 155B after flowers have fully matured. Thecomparison variety’s tonality is White Group 155B. The flower diameterof ‘Poulpah111’ is 90 mm, while the comparison variety is 70 mm. Theflower petal count for the claimed plant is 60, while the comparison is45.
